Twenty-six-year-old Amanda Hein, of Allentown, was ordered to stand trial on a criminal homicide count after a preliminary hearing Monday.
A cleaning crew found the baby's body in the toilet on Aug. 19 at Starters Pub in Bethlehem, about 30 miles north of Philadelphia. A coroner concluded the boy was born alive.
Police say they traced blood found in a bar booth to Hein. Investigators say she couldn't give them a reason she allegedly killed the baby except that she was "scared."
A message left for Hein's public defender, Michael Corriere, wasn't immediately returned.
